In addition, the terms "installation", "connection", "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific situations.

[0032] When the ball quick-opening socket wrench for throttle valves in the embodiment of the present application is in the wrench state, the pin 4 is located at the first limiting portion 521, the sliding sleeve 5 presses against the fixed sleeve 2, and the balls 3 are restricted within the fixed sleeve 2, so that part of the balls 3 extends into the interior of the fixed sleeve 2; when the ball quick-opening socket wrench for throttle valves in the embodiment of the present application is in the socket state, the sliding sleeve 5 is pulled and twisted so that the pin 4 is located at the second limiting portion 522, thereby forming a receiving space outside the balls 3 between the annular groove 51 and the mounting hole 21, and further enabling the balls 3 to be in the receiving space.

[0033] The embodiment of the present application provides a ball quick-opening socket wrench for throttle valves, as Figures 1 to 9 shown. The ball quick-opening socket wrench for throttle valves includes a rotating assembly 1, a fixed sleeve 2, a sliding sleeve 5, a pin 4, and at least two balls 3. The fixed sleeve 2 is fixedly connected to one end of the rotating assembly 1, and at least two mounting holes 21 are evenly arranged in the circumferential direction on the side away from the rotating assembly 1. At least two balls 3 are respectively located in the mounting holes 21, and their diameters are larger than the aperture on the side of the mounting holes 21 close to the inner wall of the fixed sleeve 2, so that the balls 3 will not fall into the interior of the fixed sleeve 2. Specifically, when it is necessary to disassemble or install the throttle nozzle 10, the two balls 3 at symmetrical positions extending into the interior of the fixed sleeve 2 can abut against the corners of the throttle nozzle 10, and then by rotating the rotating assembly 1, the throttle nozzle 10 can be loosened or tightened. The balls 3 are spherical parts made of steel, also called steel balls.

[0034] As Figure 2 and Figure 4As shown in the figure, six mounting holes 21 are evenly distributed circumferentially on the fixed sleeve 2 of the embodiment of the present application, and six balls 3 are accommodated therein. When it is necessary to disassemble or install the throttle nozzle 10, the six balls 3 extending into the interior of the fixed sleeve 2 can abut against the outer hexagonal edge of the throttle nozzle 10, and then by rotating the rotating assembly 1, the throttle nozzle 10 can be loosened or tightened.

[0035] As Figure 6A shown, the sliding sleeve 5 is sleeved on the fixed sleeve 2 and the rotating assembly 1. An annular groove 51 matching the mounting hole 21 is provided on the inner wall of the sliding sleeve 5, and a limiting hole 52 is provided circumferentially on the sliding sleeve 5. And a pin 4 is connected to the rotating assembly 1 and snapped into the limiting hole 52. Among them, as Figure 1 shown, the limiting hole 52 includes a first limiting portion 521 and a second limiting portion 522 that communicate with each other. The first limiting portion 521 extends along the axial direction of the sliding sleeve 5, and the second limiting portion 522 extends along the circumferential direction of the sliding sleeve 5. When the pin 4 is located in the first limiting portion 521, the sliding sleeve 5 presses against the fixed sleeve 2, and part of the ball 3 extends into the interior of the fixed sleeve 2; when the pin 4 is located in the second limiting portion 522, the annular groove 51 corresponds to the mounting hole 21 and forms an accommodating space to enable the ball 3 to be located in the accommodating space.

[0036] In one implementation manner of the embodiment of the present application, as Figure 3 and Figure 7A shown, two limiting holes 52 are evenly distributed circumferentially on the sliding sleeve 5, and both ends of the pin 4 are snapped into the two limiting holes 52 respectively. Specifically, the rotating assembly 1 is provided with a rotating hole, and the pin 4 passes through the rotating hole and is snapped into the two limiting holes 52. Of course, the embodiment of the present application is not limited to the above structure. The rotating assembly 1 may not be provided with a rotating hole, and two pins 4 corresponding to the limiting holes 52 may be provided on both sides of the rotating assembly 1.

[0037] Of course, the sliding sleeve 5 may also be provided with one limiting hole 52, the rotating assembly 1 is provided with a pin 4 corresponding to the limiting hole 52, and the pin 4 can be snapped into the limiting hole 52.

[0038] In the actual operation of this ball quick-opening socket wrench for throttle valves, when the pin 4 is located in the first limiting portion 521, the sliding sleeve 5 presses against the fixed sleeve 2, restricting the ball 3 within the fixed sleeve 2 so that part of the ball 3 extends into the interior of the fixed sleeve 2. By rotating the rotating assembly 1, the extended part of the ball 3 drives the throttle nozzle 10 to perform a rotational motion, so that all the threads of the throttle nozzle 10 are unscrewed; secondly, as Figure 8 shown, pull and twist the sliding sleeve 5 until the pin 4 is located in the second limiting portion 522. The annular groove 51 and the mounting hole 21 form an accommodating space outside the ball 3, enabling the ball 3 to be located in the accommodating space; finally, as Figure 9As shown, lower the ball quick-opening socket wrench for the throttle valve until the throttle nozzle 10 completely enters the interior of the fixed sleeve 2. Rotate the sliding sleeve 5 so that the pin 4 is located at the first limiting portion 521. At this time, part of the ball 3 extends into the interior of the fixed sleeve 2, causing the ball 3 to snap into the lower bottom surface of the throttle nozzle 10 and hook onto the lower bottom surface of the throttle nozzle 10. Pull the rotating assembly 1 to remove the throttle nozzle 10 in the cavity of the fixed throttle valve 9. If it is necessary to install the throttle nozzle 10, reverse the above steps. In the embodiment of the present application, the movement of the sliding sleeve 5 is used to limit the movement space of the ball 3 on the fixed sleeve 2, so that the throttle nozzle 10 in the fixed throttle valve 9 is detached from its connection part by relying on different positions of the ball 3 on the fixed sleeve 2, and then the throttle nozzle 10 can be grabbed. The embodiment of the present application is applicable to disassembling and grasping components in a narrow space. Therefore, the ball quick-opening socket wrench for the throttle valve in the embodiment of the present application does not need to disassemble and install the throttle nozzle 10 by increasing the inner cavity of the fixed throttle valve 9, thereby reducing the volume of the fixed throttle valve 9, and further reducing the weight and cost of the fixed throttle valve 9, which is economical, practical, convenient and fast.

[0039] The ball quick-opening socket wrench for the throttle valve further includes an elastic member 6. Both ends of the elastic member 6 are respectively connected to the rotating assembly 1 and the sliding sleeve 5, and are configured to apply an elastic force to the sliding sleeve 5 in the direction of driving part of the ball 3 to extend into the interior of the fixed sleeve 2. Specifically, as Figure 2 shown, one end of the elastic member 6 is connected to the outer top wall of the sliding sleeve 5, and the other end is connected to the side of the rotating assembly 1 away from the fixed sleeve 2. When the pin 4 is located at the end of the first limiting portion 521 close to the elastic member 6, the sliding sleeve 5 will, under the action of the compressive elastic force of the elastic member 6, cause the pin 4 to always snap into the end of the first limiting portion 521 close to the elastic member 6, so that the sliding sleeve 5 presses against the fixed sleeve 2, and further causes part of the ball 3 to extend into the interior of the fixed sleeve 2.

[0040] Of course, the embodiment of the present application is not limited to the above structure. The elastic member 6 can be located inside the sliding sleeve 5, with one end connected to the inner top wall of the sliding sleeve 5 and the other end connected to the rotating assembly 1 and close to the side of the fixed sleeve 2. When the pin 4 is located at the end of the first limiting portion 521 close to the elastic member 6, the sliding sleeve 5 will, under the action of the tensile force of the elastic member 6, cause the pin 4 to always snap into the end of the first limiting portion 521 close to the elastic member 6, so that the sliding sleeve 5 presses against the fixed sleeve 2, and further causes part of the ball 3 to extend into the interior of the fixed sleeve 2.

[0041] As Figure 3As shown, a step 11 is provided on the part of the rotating assembly 1 located outside the sliding sleeve 5. Both ends of the elastic member 6 are respectively abutted against the step 11 and the end face of the sliding sleeve 5 to apply elasticity to the sliding sleeve 5 in a direction away from the step 11. Specifically, the rotating assembly 1 of the embodiment of the present application can be provided with two cylindrical segments of different diameters, thereby forming the step 11.

[0042] As Figure 6A shown, the ball quick-opening socket wrench for throttle valve further includes a limit ring 7. The limit ring 7 abuts against the step 11. One end of the elastic member 6 abuts against the limit ring 7. The limit ring 7 penetrates from the side of the rotating assembly 1 close to the fixed sleeve 2 and is snapped into the step 11. The limit ring 7 can limit the movement of the elastic member 6, making the whole structure more stable.

[0043] Continue to refer to Figure 6A shown, the ball quick-opening socket wrench for throttle valve further includes a spring cylinder 8. The spring cylinder 8 is fixedly connected to the side of the sliding sleeve 5 away from the fixed sleeve 2, and the elastic member 6 and the limit ring 7 are located inside the spring cylinder 8. On the one hand, the spring cylinder 8 can protect the elastic member 6 from being contaminated; on the other hand, it can slide together with the sliding sleeve 5. When the operator moves the spring cylinder 8, the sliding sleeve 5 also moves together, as Figure 8 and Figure 9 shown, making the ball quick-opening socket wrench for throttle valve more convenient to use.

[0044] As Figure 1 shown, the rotating assembly 1 includes a handle 13 and a rotating rod 12. One end of the rotating rod 12 is fixedly connected to the fixed sleeve 2, and the other end of the rotating rod 12 is fixedly connected to the handle 13. One end of the pin 4 is connected to the rotating rod 12. The handle 13 makes it easier for the operator to rotate the rotating rod 12.

[0045] As Figure 3 and Figure 4 shown, the rotating assembly 1 further includes a first nut 14. A first threaded section 121 is provided on the side of the rotating rod 12 away from the fixed sleeve 2. The handle 13 is provided with a first fixing hole 131 corresponding to the first threaded section 121. The first threaded section 121 passes through the first fixing hole 131 and the handle 13 is pressed against the rotating rod 12 by the first nut 14. Specifically, the first nut 14 is a cap nut.

[0046] Furthermore, as Figure 3As shown, on the side of the rotating rod 12 away from the fixed sleeve 2, there is a section of external hexagonal cylindrical section. On the side of the external hexagonal cylindrical section close to the handle 13, there is a first threaded section 121. In the middle of the handle 13, there is a first fixing hole 131, which can be an internal hexagonal hole. The external hexagonal cylindrical section passes through the internal hexagonal hole in the middle of the handle 13 and forms a fit with the internal hexagonal hole. The internal thread in the cap nut cooperates with the first threaded section 121 of the rotating rod 12 to press the handle 13 onto the rotating rod 12.

[0047] As Figure 2 and Figure 3 shown, the ball quick-opening socket wrench for throttle valve further includes an elastic gasket 16 and a second nut 15. On the side of the rotating rod 12 facing the fixed sleeve 2, there is a second threaded section 122. The fixed sleeve 2 is provided with a second fixing hole 22 corresponding to the second threaded section 122. The second threaded section 122 passes through the second fixing hole 22, and the fixed sleeve 2 is pressed onto the rotating assembly 1 through the elastic gasket 16 and the second nut 15.

[0048] Further, on the side of the rotating rod 12 away from the handle 13, there is an external hexagonal cylindrical section. On the side of the external hexagonal cylindrical section close to the fixed sleeve 2, there is a second threaded section 122. As Figure 4 shown, on the top wall of the side of the fixed sleeve 2 close to the rotating assembly 1, there is a second fixing hole 22, which can be an internal hexagonal hole. The second threaded section 122 passes through the internal hexagonal hole on the fixed sleeve 2, and the external hexagonal cylindrical section cooperates with the internal hexagonal hole. The elastic gasket 16 and the second nut 15 cooperate with the second threaded section 122 to press the fixed sleeve 2 onto the rotating rod 12.

[0049] As Figures 6A to 7C shown, the limiting hole 52 is a T-shaped hole. The second limiting part 522 of the T-shaped hole is close to the fixed sleeve 2. The first limiting part 521 of the T-shaped hole is close to the elastic member 6. The annular groove 51 is located at the end of the sliding sleeve 5. When the plug pin 4 is at the end of the first limiting part 521 close to the elastic member 6, the side of the sliding sleeve 5 away from the elastic member 6 is flush with the side of the fixed sleeve 2 away from the rotating assembly 1; when the plug pin 4 is at the end of any side of the second limiting part 522, the annular groove 51 corresponds to the mounting hole 21 and forms an accommodating space to enable the ball 3 to be located in the accommodating space.

[0050] In one implementation manner of the embodiment of the present application, as Figure 9 shown, when the sliding sleeve 5 is flush with one side of the fixed sleeve 2, the ball quick-opening socket wrench for throttle valve is in the wrench state; as Figure 8 shown, when the sliding sleeve 5 is pulled and twisted, the sliding sleeve 5 moves upward, so that the annular groove 51 and the mounting hole 21 form an accommodating space outside the steel ball, and the ball quick-opening socket wrench for throttle valve is in the sleeve state.

[0051] In actual operation of the ball quick-opening socket wrench for the throttle valve, first, when the pin 4 moves to the end near the elastic member 6 of the first limiting portion 521, the sliding sleeve 5 will, under the action of the compressive elastic force of the elastic member 6, cause the pin 4 to always be stuck at the end near the elastic member 6 of the first limiting portion 521. The ball 3 is restricted within the fixed sleeve 2 by the sliding sleeve 5, such that a part of the ball 3 extends into the interior of the fixed sleeve 2. Rotate the rotating assembly 1, and the ball 3 extending into the interior of the fixed sleeve 2 drives the throttle nozzle 10 to perform a rotational movement, so that all the threads of the throttle nozzle 10 are unscrewed. Secondly, pull and twist the sliding sleeve 5 so that the pin 4 is located at the end on either side of the second limiting portion 522. The annular groove 51 and the mounting hole 21 form a receiving space outside the ball 3, so that the ball 3 is located within the receiving space. Finally, lower the ball quick-opening socket wrench for the throttle valve until the throttle nozzle 10 completely enters the interior of the fixed sleeve 2. Rotate the sliding sleeve 5, such that the pin 4 will move along the second limiting portion 522 until it moves to the connection between the second limiting portion 522 and the first limiting portion 521, and under the action of the compressive elastic force of the elastic member 6, it will return to the end near the elastic member 6 of the first limiting portion 521. At the same time, lower the sliding sleeve 5 so that one side of the sliding sleeve 5 is flush with the fixed sleeve 2. At this time, a part of the ball 3 extends into the interior of the fixed sleeve 2, and is stuck into the lower bottom surface of the throttle nozzle 10 and hooks the lower bottom surface of the throttle nozzle 10. Pull the rotating assembly 1 to take out the throttle nozzle 10 in the cavity of the fixed throttle valve 9. If it is necessary to install the throttle nozzle 10, just operate the above steps in reverse.

[0052] In one implementation manner of the embodiment of the present application, the mounting hole 21 is a tapered hole, and the aperture at the bottom of the tapered hole is smaller than the diameter of the ball 3, such that the ball 3 will not fall into the interior of the fixed sleeve 2. Of course, the embodiment of the present application is not limited to the tapered hole. The mounting hole 21 may also be composed of two L-shaped holes, and there is a certain distance reserved at the bottom of the two L-shaped holes, and this distance is smaller than the diameter of the ball 3, such that the ball 3 will not fall into the interior of the fixed sleeve 2.

[0053] The various embodiments in this specification are described in a progressive manner. For the same or similar parts between the various embodiments, reference can be made to each other. The key point of each embodiment is to illustrate the differences from other embodiments.
